Ability to make decisions using validated real time data is known as a base tier of a digital oilfield. The goal of digitalization is enhancing oil production and cost reducing. But for mature onshore fields with thousands of producing wells with low oil rates upgrading the data acquisition system may be economically unreasonable.

This paper describes the methodology of gauge configuration value estimation using the value of information concept. The main idea of the research is that additional information has value only when it drives to new well works or you can make right decision faster.

Authors analyzed statistics of a general well works on the ESP-producing oil wells (including costs and effects) and distinguished the datasets (and gauge configurations) needed to make decisions about well intervention. Results of a gauge configuration value estimation for considered onshore field are shown as a pallet that allow to choose most economically reasonable configuration using oil rate and mean time to failure parameters. Complex of low oil rate and normal MTTF values assign that there are no economic reasons to upgrade actual gauges configuration. Before using these results for investment decision it’s necessary to analyze fact well works effects, cost and nomenclature of gauges and actual business-processes in company conditions.
